AUTOMATIC OIL-SAVER.

To all whom it may concern:

Be it known that I, WiLLiAM H. JAcoBs, a citizen of the United States, residin at Au sta,iin the county of Butler and tate of ansas', have invented certain new and useful Improvements in Automatic Oil- Savers, of which the following is a specifi- In the stoia e of oil in quantity, considerable loss and damage are experienced in the event of fire eitherby the direct loss of the oil contained in the tankon fire or by conimunica'tion of the fire from one tank to another. The present invention primarily aims to save the oil contained in the tank which is on fire and incidentally to ,prevent the lire bein communicated from such tank to other tanis or property in the immediate vicinity by the flowing of the burning oil from the tank on fire to other tanks or property. p

The invention provides automatic, means which are rendered active in the event of fire or in the presence of excessive heat 'whereby an escape is provided for the oil from the tank on fire.

The invention furthermore provides an automatic cut-off for the escaping oil whereby fire is prevented from being communicated from the burning tank to the tank or receptacle into which the oil is escaping, such cut-ofi being brought into operation when the oil in the burning tank reaches a low level therein tending to permit burning oil to escape and result in asp'read of the The invention provides a novel valve inechanism and automatically operated means in conjunction therewith, the saine bein actuated by abnorinalheat as 'ja result of re.

The drawing illustrates a preferred ein'- bodiment of the invention, however, it is to be understood that in adaptingthe same to meet different conditions, various changes in the form, proportion, and minor details of construction may be resorted to IWithout departing from the nature of the invention as claimed hereinafter.'

description and indicated to in the following o the drawings by like ref- "tank, A may ,discharge in an emergency.

The pipe 2 is provide in its length with a relief valve 3 and a cut-olf valve 4l, the relief valve being disposed at a point between the tank -A and the cut-oii` valve 4. The valves approved construction and toy avoid con usion, they are designated by terms descriptive of their function. When the oil is escaping from the tank A, both valves and when the level of the tank A reaches a point of 4, automatically closes,

burning oil in the danger, the valve thereby Vcutting oi the out-ofw of the goil from the tank A and preventing -lire being ycommunicated from such tank to the tank oi* container into which the oil is escaping. i

In the drawing, the valves 3 and 4 are illustrated asv embodying a gate 5 andthe valve 4c embodying a gate-6. A .stem 7 projects from the gate 5 and passes through the casing of the valve and receives an expansible helical between the valve casin and a stop 9 at' the l stein Undernormal conditionsythe's ring 8 holds the. gate valve 5 in open position. This valve however,` is `held in closed position by suitable means which are automatically 4released under abnormal conditions, whereby the valve is permitted to open,

of the gate type, the' valve 3- v".60 Corresponding and like parte are referred escape for the 'engaged at its free end freerthe valve l thereby providing an escape for the oi-l from the tank A through the pipe 2. As shown, the connecting means embody a plurality of bell cranks 12, 13, and 14, the latter being disposed'near the relief valve 3 and having anarm connected to the catch 11 by means of a link 15. IThe bell crank 13 is disposed near the top ofthe vvtank and at the sid'e thereof, anda link 16 Aconnects one arm Y is connected to thereof with the remaining army ofthe bell 'crank 14. A link 17 connects .thercmaining arm'of the bellfcrank iliivith `an arm of .the ilnikllgllih latten is preferably 4'disposed Within the upper portion ofv the tank. A rod or like member 18 is'positioned to engage the remaining or horizontal arm of the bell crank'12 andpasses through an opening in thel upper end of such arm. A Weight 19 is attached 'to the lower end of the. rod 18 and the upper end of such rod the super-structu`re 1 by vmeans of a fusible link or connector 21. which' maybe of lead or composition of a nature to melt at a relatively low temperature so that'in the event l of a fire, the-link or connector -21 Will be destroyed thereby releasing the rod 18V which descends by gravity force and operates the bellcrank 12 and effectsa 'release of the' `latch 10 through the intermediate connections between the bell crank 12 and the catch 111 The rod 18 operates through an openiug in the top of the tank and its upper end is vexpanded and constitutes a stop which impants' "with thefhorizontal'arm -ef the bell crfink 12, so as'to operate'the latter when the weight 19 is released and drops.'

The cli-troll valve'f4 as hereinbefore stated is .of similar construction to the' relief valve 3 and under normal co'nditionswis held 'in .open position, but under certainV conditions the valve l:bis permitted to fautonlatically close and cut uit thc-'How of oil through the L relief pipe 2. A-stem`22- extends :from

the gate ,jthrough the casing ofthe valve' .4 and'passes tliroughag-oke 23 and is provided at its upper end with 'anzeye Which- -engages'one arm of bel-l. crank 24. The

remainingkarmofthe bell Acrank 24 is con- Y. nected by means cfa linlo25- with a bell crank ,26 disposed. in Within the tank A y tion above'the bottom thereof and' supported a casing fxarrz-mged `vat ,a 'predetermined posiwhichy the link 25 passes."

gate 6 ofthe cut-off 'valve against the tension of the '.the` yoke 23 with theends an element 2() supported in'- the tank A to ad upon a suitable stand 28. A tube'29 forms' for the link 25 and connects thel a housing casing"y 27 and side of `the tank A through A fusible link or connector 30 joins onearm of the bell crank 26 with the 'casing 27 and normally holds the 4 in open position closing means, the latter consisting of a pair cal springs 31 which connect the ends of of. a companion yoke 32 at thevlower end of the valve cas. ingv4. In the practical operation of the invention, the parts being assembledv and disposed in the' manner=,hereinbefore specified and illustrated inthe drawing, the tank A is supplied with the o il tovbe stored therein. Under normal conditions,the cut-olf valve 4 is lheld inopen position against the tension ,of the springs 3l and the relief valve 5 is heldy closed against the tension ofthe spring 8,.v Under {lonely-mal conditions, resulting fronifire, or excessive heat, suilicient to melt Athe iusiblc connector 21, the 'Weight 19 drops and actu-etes thebell crank 12 and effects disengagement of the catch 11 from the latch 10, thereby` permitting the relief valve to open and the oil to pass from the tank A, through the relioil pipe 2" into a tank orother receiving containernot shown. Should the oil be on fire, the fiume the Connector 30 wwhen in the tankA reaches the casing 27 hence the cut-QH valve 7 automatically closesand shuts off'the out-flow ofv .the oil and prevents the burning. fluid, from passing the level of the oil through the pipe 2. int0 the reservoincontamcr, or receptacle intofwhich the oil is result that the fire is being communicated from jacent property.
